Sgt. Michael Giampietro

Sgt. Michael Giampietro, a 14-year veteran of the force, faces a charge of aggravated assault. He waived his first court appearance, originally scheduled for Thursday, and a future hearing date has not been set, said his attorney, Bob Galuntucci.

Giampietro, 37, is accused of walking up behind another officer, who was talking to a third party, and striking him in the jaw, according to the Bergen County Prosecutor’s Office. The March 28 incident took place outside a River Edge residence while both officers were off duty, according to authorities. Investigators have not revealed the other officer’s identity because he is considered the victim.

Galuntucci said Wednesday that the facts in the case were still being gathered.

“I’m confident that this matter will be resolved and Officer Giampietro will continue to be a well-deserving public servant,” the attorney said.

The sergeant has not been suspended from his $124,211-per-year job and is currently assigned to an administrative post, said Cliffside Park spokesman Bill Maer.

Giampietro is subject to a departmental review, Maer noted, adding that the Police Department is following state guidelines for handling such matters. The officer has no prior disciplinary record with the department.
